Rudeus Greyrat's adventures on the Demon Continent take a startling turn when he crosses paths with the Great Emperor of the Demon World, Kishirika Kishirisu. In gratitude for his help, she grants him a mysterious "demon eye" that lets him glimpse the future--an ability that proves as dangerous as it is powerful. Armed with this new gift, Rudeus reunites with his companions Eris and Ruijerd to press onward toward home. But in the Holy Country of Millis, a shocking encounter pits father against son, and in the Shirone Kingdom, a desperate rescue mission for Lilia and Aisha draws Rudeus into royal intrigue--and forces the Dead End party to confront an emotional farewell.
